In the context of maintaining unity (Eph 4.3) and attaining to unity (v13) we are commanded to be humble and gentle and patient and to bear with one another in love.
Unity is not achieved by us lording it over others; nor by demanding loyalty or subservience.
True unity is both sweet and powerful.

Verse 13 links unity with the character of Christ; the ultimate goal of gifted men and women serving amongst us.
Verse 13 refers to ‘knowledge;’ verse 15 to ‘truth.’ We do not diminish truth; we do not seek a lowest common denominator; we find the truth in Christ; we are no longer buffeted by false doctrines; we enjoy clarity nor confusion.
And, in v16, we all play our part – the whole body is involved and each part does its share.
And, as diversity increases, we will need to work harder at unity. And that is a good thing!
